While there is much debate on which form is better, this 2015 study (http://file.scirp.org/pdf/PP_2015021016351567.pdf) leans in favor of Full Spectrum products. There are many that believe that other cannabinoids, THC especially, are necessary to take full advantage of what cannabis has to offer. Ultimately, however, we are all different and it comes down to the individual user and their needs. If drug testing is a concern, you’re encouraged to seek out CBD isolate products (or terpsolates) instead of Full Spectrum.
You may have read or heard in the news all the reports of people wanting to take CBD Oil for many ailments, some of which are cancer, epilepsy, chronic pain, TMJ, anxiety and diabetes. And, many people are reporting some pretty fantastic improvements to their conditions after taking these oils. The first thing most people want to know is: IS THERE ANY DIFFERENCE BETWEEN CANNABIDIOL FROM HEMP AND CANNABIDIOL FROM MARIJUANA? And, the short answer is “no”; molecularly, CBD is CBD. But, there are generally some differences in the CBD Extracts. Let me explain this a bit further.
The first step to finding your correct CBD dosage is getting as much information as you can about the product you’re using. What is the concentration of CBD? Are there third-party lab tests that can confirm that? The CBD industry is still mainly a grassroots therapeutic movement, and as such, largely unregulated. Concentration and purity levels can differ greatly depending on the manufacturing process.
Full spectrum CBD does, however, bring with it the sticky issue of THC. The government regulates concentration levels of THC at 0.3 percent, an amount which results in minimal psychoactivity. But THC metabolites are stored in the fat cells of your body, building up over time. If you ever need to take a drug test, this could create an issue for you.
While it is clear that full spectrum CBD may be more effective than isolate CBD, even at lower dosages, it may have some drawbacks. Full spectrum vs regular CBD comes down to this drawback for many people. If full spectrum CBD oil is not an option for you due to your obligations or lifestyle, this can help you make your decision more easily for sure.

The aforementioned entourage effect is the main reason behind the efficacy of whole plant extracts. There are over 100 ‘identified’ compounds in the cannabis plant. While most of these compounds have their own therapeutic benefit, they combine synergistically to provide a far better performance than any single compound, including CBD. Here are a couple of examples of conditions that benefit from the entourage effect:
